Sons 99 Regal GS transmission is going bad. Revs up in first gear then engages about 2000 rpm . Will slip in first if you accelerate hard . Once going in 2,3,4 its normal until you stop again. Only DTC codes are MAF sensor low. Slightly better after warm. Checked pressure solenoid resistance normal at 5 ohms. Reset PCM plugs, no change . Everything was normal 3000 ago after routine trans fluid change. Then after about 1000 miles started acting up. Pulled pan, slight amount of burnt friction material. Fluid turning brown . New fluid ad filter did not improve things.

Any opinions?
